How Japanese J Names Work

Japanese J names use the sounds Ja, Ji, Ju and Jo. Most of them come from kanji like Jun 純, Jin 仁, Jō 丈 and Jūrō 十郎. The J sound mostly appears in words of Chinese origin and in loanwords, and almost never starts a native Japanese word. That is why there are fewer Japanese names that start with J than names starting with K or S, and why every real one stands out.

Common kanji you will see

Jun: 純 pure, 潤 abundant, 淳 sincere
Jin: 仁 kindness, 迅 swift, 神 god
Jō: 丈 height, 城 castle, 譲 yielding, 穣 abundance
Jū: 十 ten, 柔 gentle, 重 esteemed
Ju: 樹 tree, 寿 long life
Ji: 次 next, 慈 mercy, 治 govern, 自 self
Jitsu: 実 real, true

How to say a J name

J sounds like the “j” in “jam,” so Jun is “joon.”
Ji is “jee,” Ju is “joo,” Jo is “joh” and Ja is “jah.”
A line over a vowel (ō, ū) means say it a bit longer, so Jūrō is “joo-roh.”
An apostrophe, like in Jun’ichi, just splits the sounds: “joon-ee-chee.”
Names like Jirō (second son) and Jūrō (tenth son) come from an old tradition of naming sons by birth order.
In plain text, Jūrō is often typed as Juro or Jurou.

How To Choose A Japanese J Name

Picking from Japanese names that start with J is easy when you think about sound, kanji and purpose. Start with the feeling you want, then check the meaning and how the name sounds with your last name.

Decide what the name is for: a baby, a pet, a character or a username.
Pick the kanji first. Jun can mean pure (純), abundant (潤) or sincere (淳).
Say it out loud. The J should sound like the “j” in “jam.”
Match it to your last name. Short names like Jin or Juri sound best next to long family names.
Real or creative? Use the names with no label for a child, and the words or (creative) names for stories.
If you plan to register a child’s name in Japan, the kanji must come from the official approved lists, so check every character first.
